This invention relates to improvements in talking machines and more particularly to a device which may be attached to conventional talking machines to adapt same for reproducing, in successive order and at separate intervals of time, portions of a sound record.

The object of my invention is to produce a device which ma be conveniently attached to conventional ta king machines and which may be used for playing successively and at separate intervals of time, a plurality of selections or parts of the matter contained on one record; a device which may be manually or automatically put into operation; in which, after the operation has been started, a tone arm and needle will be automatically lowered into operative relation to the record, but not until SUfllClGllttime has elapsed for the turn table carrying the record to have gained proper momentum so that, as soon as the needle contacts wit-h the record, that part of the record to be played will be efficiently reproduced; and in which, after the needle has traversed a predetermined portion of the record, brake mechanismwill be auton'iatically actuated to stop the rotation of the turn table and record and, simultaneously or almost simultaneously with the actuating of the brake mechanism, the tone arm carrying the needle will be automatically raised from contact with the record and held in raised position, ready to be automatically lowered to resume the reproduction of the next selection or part of the record when the cycle of operations is repeated.

A practical application of my invention may consist of operat-ively connecting the device with time-controlled mechanism which may, for example, put the device into operation hourly and be used with a sound record carrying certain matter, parts of which are fitting to be reproduced successively at hourly or other intervals of time.

lt vill be understood that the recordsto be used with my device will be especially prepared for particular purposes and that the matter to be reproduced at one time will be slightly spaced from the matter on the same record to be subsequently reproduced.

The device embodies means such as a spring motor or electric motor for actuating the turn table; mechanism driven by the turn table and operatively connected with'means for automatically placing the needle in operative relation to the record afterthe turn table has gained momentum; means for latching, the needle support in operative posit-ion; means adjustable according to the matter on the record, and actuated by the needle, to automatically actuate means for closing an elec: tric circuit, whereby a solenoid is energized and instantly actuates means connected with a brake mechanism for stopping the rotation of the turn table and also actuates the r means for unlatching the needle support and for automatically raising the needle from contact with the record.

Figure 11 is a vertical section taken on the line 11-11 of Figure 10, looking in the direction indicated by the arrows.

r I have said that Figure 2 shows the operative'p-ositions of the parts and this is true except that the switch lever, (designated 88) shown in the lowered,contacting position, is in said position for only a moment during the operation. The rest of the time the switch is open, asshown in Figure 3.

In that embodiment of my invention shown in the drawings, 20 is a support which may be the usual table used to rotatably support a turn table 21. An electric motor 22 is located below the support 20, and is operatively connected to the turn table 21 to rotate the same. A record 23 is supported upon the turn table 21 to rotate therewith. The usual tone arm or reproducer 24 carries a needle 25. The tone arm, of course, communicates with the usual sound conduit or horn, not shown.

A U-shaped frame indicated as a whole 1 at 26 is located above and rigidly secured to the table 20. The frame has downwardly extending portions 27 and 28, to which is secured a rod 29. Pivotally connectedat 30, to the shaft 29, is a supplemental frame comprisin a curved bar 31 and arms 32 and 33. n adjustable member 34 is connected to the tone arm 24 and rests upon the curved bar 31 of the supplemental frame, to support the tone arm upon said frame when at rest in raised position. When the needle is in operation, the frame bar 31 is out of contact with the attachment 34.

The supplemental frame arm 33 rests upon the upper end of a vertically movable rod 35, notched at 36. The lower end of this rod 35 engages a control bar 37 having a raised, inclined surface 38 at one end. The Vertical rod 35 is raised by this wedge-like or cam surface 38 when the control bar 37 is pulled to one side, that is toward the top in Figure 1, by the action of the spring 39 wrapped about the stud 40, connected to said bar 37 and to the table 20, and said vertical rod 35 is lowered when the control bar 37 is pushed in the other direction, that is, toward the bottom of Figure 1, to remove the wedge or cam surface 38 from beneath the rod 35. i

The bar 37 is moved in one direction, by what may be called the governor mechanism;

that is, mechanism driven from the turn table 21 and operatively connected to the means just described for automatically lowering the needle into operative relation to the vrecord. The purpose of this governor is to delay the placing of the needle into operative position until the turn table 21 has gained proper momentum.

The governor comprises a drivewheel 41 which, in Figure 1, is shown in contact with the turn table 21. Said drive wheel meshes with a pinion 42 on shaft 43, said pinion 42 meshing with the spur gear 44 on shaft 45. The spur gear 44 has fixedly secured to it a cam 46 which engages a roller 47 connected to a bar 48, slotted at 49, the side margins of the slot engaging the shaft 45. The slotted bar 48 is provided with a cam surface 50 at one end, the cam 50 being adapted to engage a roller 51 on one end of an elongated arm 52 pivotally mounted at 53 to the table 20. The other end of the arm 52 engages and actuates the control bar 37 by which the-vertical rod 35 is lowered and raised.

In the operation of this part of the mechanism, the turn table 21 drives the wheel 41 in the direction indicated in Figure 10. Said wheel through the pinion 43 drives the spur gear 44 to which the cam 46 is attached. The cam 46 at the beginning of the operation will have its concentric surface, indicated at 46', in engagement with the roller 47 on the slotted bar 48. This is shown in one of the dotted line positions of Figure 10, namely, that toward the left. After the cam has almost made a complete rotation, the parts will be in the position shown in full lines in Figure 10, the turn table will have gained momentum, and the slotted bar 48 will have been moved outwardly by the cam 46, to second position, where it actuates the pivoted bar 52, which pushes the control bar 37, allowing the tone arm and needle to drop; then, under the influence of the coiled spring 54, connected to the cam 50 and stationary frame 55, the slotted bar 48 will assume the third, or other dotted line position nearer the right of Figure 10, so as to bring said slotted bar 48 into contact with the pivoted lever 56. The end 56 functions as a brake against the drive wheel 41 and pushes said wheel from engagement with the turn table 21. This pivoted brake lever 56 is connected to the fixed frame 55, whereas the rest of the governor mechanism and the frame 57 to which it is connected have a slight pivotal movement about the pivot 58, for the purpose of allowing the brake 56 to push the governor mechanism, including the drive Wheel, from engagement with the turn table 21. After the governor parts have been thus actuated to third position, the turn table is free to rotate until other brake means is applied, as will be explained, after a predetermined part of the record has been played. 7

When the vertical rod 35 has been lowered by the actuating of the control bar 37, whereby the needle 25 is broughtv into operative relation to the record 23, said vertical rod is latched in its lowered position by the following means: A dog 59 ispivotally connected at to a housing or support 61, and said dog 59 is pressed by a spring 62 against a vertical rod 35, so that when in the clownward movement-of the rod 35 the notch 36 comes opposite the dog 59, the lever engages the. notch surface and holds the rod 35 in its lowered position as shown in Figure 2.

The foregoing describes the operative positions of the parts when the record is being played, the governor mechanism having already functioned, and the control bar 37 having been moved so that its cam or wedge surface 38 has been pushed outwardly away from the vertical rod 35, thereby permitting the tone arm support 31 to drop and place the needle 25 into operative relation to the record, in which position said vertical rod 35 is latched by the dog 59 engaging the notch 36.

It will now be in order to describe the meansfor automatically stopping the playing of the record when the end of that part intended to be played has beenreached. Referring more particularly to Figures 8 and 9, it will be seen that at one side of the pivoted arm 32 ofthe tone arm support, there is a second arm 63 which extends forwardly and slightly downwardly from the rod 29. There is secured to this arm'63 a flat spring 64. The

arm 63 is held in adjusted position by aplunger 65 extending through a bracket 66 rigidly secured to the support- 28, and spring-pressed at 67 to hold the end of the plunger 65 in an aperture in the arm 63. The end of the arm 63 is slithorizontally, near the point indicated at 68.

A stop bar 69, carrying a-djustably located stop devices 70 having needle engaging points 71, has one of its ends inserted in the slot 68 of the arm 63 so as to be slidably held therein by a latch 72 pivotally mounted at 73 on the arm 63. The stop bar 69 will'be so placed in the slot 68 of the arm 63 that the enlarged end 74 of said stop bar will be between the arm 63 and the flat spring 64 and capable of exercising pressure against said spring 64 when the bar is moved toward said spring.

The other end of the stop bar 69 rests upon a horizontal part of a fixed support 7 5, and extends through a slot- 7 6 in the vertical portion of said support 75. The end 77 of the stop bar 69 normally protrudes beyond the wall 75 to a very slight degree, as best shown in Figure 4. The bar 69 is held in this position by the pressure of the spring 64 against the opposite end 74 of said bar 69.

The stop devices 70 are adjustably located on the bar 69 according to the matter contained, on the record 23-; that is to say, each stop 70 is so placed that the point 71 will contact with the needle 25 when the end of a certain selection or part of the record is reached. When the machine is in operation, the needle-25, in its travel over part of the record, comes into contact with one of the stop points 7.1 and thereby moves the stop bar 69 slightly to one side (toward what appears to be the top of Figure 8) against the tension of the spring 64, whereby the end 77 of the stop bar is withdrawn from the position shown in Figure 4 and assumes that shown in Figure 5.

The effect of this slightmovement of the stop bar 69 will now be described: Mounted on top of a raised platform 78, rigidly se cured to the turn table 20, is a support. 79, having a pair of apertured ears 80. The sup port 79 carries a solenoid 81. An armature 82 is pivotally connected to the ears 80 by a pin 83. The armature 82 may be provided with a handle 84 or may be connected to timecontrolled mechanism for automatically lifting said armature 82. r

The solenoid 81 is connected to a source of electrcal power by a current wire 85 and to a contact plate or switch button 86 on the platform 78 by the wire 87. A switch lever 88 is pivotally mounted at 89 to the support 7 5, which is fixed to the part 78, its downwardly extending lug 90 normally resting upon the end 77 of the stopbar 69. The switch lever 88 has pivotally connected to it between its ends a slotted link 91, said link being movably connected to a part of the tone I arm supporting frame 33 by a bolt 92 extending through the slotted link 91,. This slotted connection permits the tone arm support to be raised and lowered withoutafi'ecting the position of the switch lever 88 while the latter is being held up by itspart 9O resting upon the end 77 of the stop bar 69, as shown in Figure 3.

lVhen the stop bar 69 is moved by contact of the needle with one of the stop points 71, the end 77 of the stop bar 69 is withdrawn from beneath the lug 90 of the switch lever 88, and said lever 88 drops to the position shown in Figure 2 (and in detail in Figure 5), closing the electric circuit by contacting with the switch button 86. The switch lever 88 is brought into the electric circuit by means of the wire 93 connected to the support 75. t The closing of the switch 86-88 energizes the solenoid 81 and causes it to draw the armature 82 toward it. This movement of the armature 82 from the position shown in Figure 2 to that in Figure 3 instantly accomplishes the following results: The end 94. of the pivotally mounted bracket 95, fixed to the armature, which is raised by the lowering of the armature 82, pulls upwardly abrake rod 96, connected to a toggle link 97, connected to a housing 98, rigidly secured to the platform 78. V The toggle is also connected to a brake shoe 99, which is adapted to engage the turn table 21. Therefore the actuating of the lever end 94 sets the brake 99 and stops the rotation of the record as soon as the electric circuit is closed by the dropping of the switch lever 88 upon plate 86.

Another result of the closing of the switch will be best understood by reference to Figures 3, 6 and 7: The lower end of a downwardly extending bar 100, rigidly secured to said lever 94, by the lifting of said lever 94, is made to contact with the end of the horizontally disposed foot 101 of a bent tripper 102, slidably mounted under the support 61, so that the end 103 of said tripper contacts with the downwardly bent portion of the dog 59, against the tension of the spring 62, to disengage said dog from the notched vertical bar 35. The foot 101 of the tripper 102 moves in a guideway 104, the bent over portions 105 on the guideway walls engaging the curved, struck-up parts 106 at the side of the tripper foot. These parts 106 act as cams in their contact with the parts 105 and cause the end of foot 101 of the tripper 102 to be depressed and disengaged by the bar 100 when the tripper 102 has functioned, before the lever 94 contacts with the frame arm 33 to lift the tone arm.

As the lever 94 continues upwardly, it strikes the lower surface of the end of the arm 33 of the tone arm frame, and liftsit and the tone arm and needle out of operative position. The moment of lost motion before the operating lever 94 contacts with the frame 33 is sufficient to release the dog 59 which engages the notch 36 in the vertical rod 35.

The releasing of the rod 35 by the tripper action just described permits the spring 39 to function to retract the control bar 37 and bring the cam surface 38 thereof under the rod 35 with the result that said rod is quickly moved upwardly toward the tone arm support and maintains it in raised position. The retracting of the control bar 37 also actuates the pivoted bar 52, causingthe roller 51 to press against the cam end of the slotted bar 48 and restore the parts of the governormechanism to their original position. The raising ofthe arm 33 of the tone arm support carries with it the switch lever 88 to the raised position shown in Figure 3.

The parts remain in this inoperative position with the brake 99 applied to the turn table, the tone arm support raised and the needle out of operative relation to the record, the switch 86-88 opened, the tripper 102 re tracted'by the hook and spring 107 from engagement with the dog 59, until the parts are again actuated by manually or automatically moving the armature upwardly and the lever 94 downwardly to the position shown in F1 gure 2.
